Modified Radio Shack Realistic PZM Microphone + Preamp Upgrade Alchemy Audio

Condition: Used, very good condition. Microphone functions properly with no issues and contains only VERY slight wear from normal, gentle use. Preamp circuit and enclosure are new.

Notes: In its stock form, the Radioshack PZM suffers from a cumbersome, under-powered battery, higher than acceptable distortion and lackluster bass response. It's also sensitive to hum fields. We begin by (literally) cutting the cord and eliminating the battery box on the end. You won't need it and certainly won't miss it. We construct a 48V phantom powered preamp circuit (from Uneeda Audio and housed inside a bare aluminum enclosure) with status LED indicator. The end result is a microphone with lower distortion, increased bass response and less sensitivity to hum fields - while running on 48V phantom power from your mixer / preamp! Not only is the mod practical but it makes these microphones sound pretty darn good. After the mod is complete, you can set these up permanently in a room (as many studios have) and utilize them whenever you'd like.
